A few weeks ago, we wrote a blog post about the Securities and Exchange Commission’s Regulation SCI, aimed at more closely regulating the IT systems running the majority of the US stock exchanges and injecting investor confidence back into the market.
As mentioned in that previous post, we believe the proposed regulation does not go far enough to ensure that the integrity and structural quality of these trading platforms are properly managed -- and the instability of these systems has been all too evident over the past week or so.
As leaders in software quality, the experts at CAST were called on by a number of leading news outlets for our comments on what we can learn from these outages, and how they could have been prevented.

"These are all highly data intensive systems. They pass information, monitor it ... if you have a complex system that manages master data, you also have multiple components that can act on that data -- change it remove it, or add it. If you're not managing the way that's handled, like you have 2 different components that manage the data, you can run into corruption issues." – Lev Lesokhin
Exchanges must improve software or risk more Nasdaq-style outages – ComputerWorld UK

Nasdaq outage: Are we playing Russian roulette with our trading platforms? – Computing UK
"The fundamental problem in some of these organizations is that they've got a trading floor with market traders who just want the systems to get things done as quickly as possible, and they don't care as much about whether they are pushing too fast, or if they are getting things into the system too quickly. It's very difficult for an IT organization to make sure their software is well engineered and not a big pile of spaghetti code; it's hard for them to test and hard for them to ensure it stays robust.” – Lev Lesokhin
